The coating device of metal can weldering ear
Technical field
The present invention relates to the spraying field of metal can, particularly relate to a kind of coating device of metal can weldering ear.
Background technology
At present, all can carry out the coating of related solution at the weldering ear place of metal can in order to prevent getting rusty of solder joint.Existing coating mode is artificial with the manual coating of brush mostly, and efficient is very low; Simultaneously, each welds the bigger subjectivity that how much has of ear coating amount, and the amount that can not hold coating each time well all is the same; In addition, also be difficult for the control time in when oven dry, and sometimes brush to be stained with solution too much, capacity causes flow of solution and makes metal can dirty.Therefore, the following shortcoming (1) of existing coating ubiquity, to take the people time-consuming, and production efficiency is low;
(2), product quality can not get maximum the assurance;
(3), the control property in the operating process is not good enough.
Summary of the invention
The object of the invention provides a kind of coating device that is used for metal can weldering ear.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of coating device of metal can weldering ear; Comprise the elasticity bottle, be installed in described elasticity bottle top connector, be installed in the lid on described connector top; Described connector inside offers pod apertures, offers blacking hole on the upper perimeter wall of described lid, and described pod apertures is connected with blacking hole; Described blacking hole outside is coated with block piece, and described block piece is selected the material of fibr tissue for use.
Preferably, described connector bottom has the interface that the bottleneck with described elasticity bottle is complementary.
Preferably, the hollow bulb that described connector middle part has a U type, described hollow bulb is connected with pod apertures.
Preferably, described connector top has a resettlement section, and described lid is installed in the described resettlement section.
Preferably, described block piece is sponge or cotton.
Because technique scheme utilization; The present invention compared with prior art has advantage and effect: the slow problem of coating that the invention solves manual brushing; And in the coating process, be more prone to control the coating amount, alleviated the difficulty of follow-up oven dry link; Simultaneously, effectively control the phenomenon that dirty product occurs, product quality is effectively promoted.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
The coating device of a kind of metal can weldering ear as shown in Figure 1, comprise elasticity bottle 1, be installed in elasticity bottle 1 top connector 2, be installed in the lid 3 on connector 2 tops.Elasticity bottle 1 can utilize commonly in the daily life has certain flexible plastic products; Connector 2 bottoms have the interface 4 that the bottleneck with elasticity bottle 1 is complementary; Connector 2 middle parts have the hollow bulb 6 of a U type, and connector 2 tops have a resettlement section 7, and connector 2 inside offer pod apertures 5; Pod apertures 5 is connected interface 4 with hollow bulb 6, as shown in Figure 2; Offer blacking hole 8 on the upper perimeter wall of lid 3, like Fig. 3, shown in 4.When lid 3 was installed in the resettlement section 7 of connector 2, blacking hole 8 was connected with pod apertures 5.In addition, blacking hole 8 outsides are coated with block piece, and block piece is selected the material of fibr tissue for use, such as being sponge or cotton.
Below the concrete method of operating of present embodiment down of setting forth:
The coating liquid of in elasticity bottle 1, packing into is fastened on the interface 4 of connector 2 on the bottleneck of elasticity bottle 1, lid 3 is installed in the resettlement section 7 of connector 2, lid 3 outside coverings such as sponge or cotton.During use, extruding elasticity bottle 1, liquid flows to hollow bulb 6 through pod apertures 5 again by flowing to pod apertures 5 in the bottle, flows into the blacking hole 8 of lid 3 at last, and blacking hole 8 is coated in the liquid commentaries on classics on sponge or the cotton, thus cotton Contact welding ear is accomplished coating.Like this, sponge or cotton also have certain cushioning effect, to prevent certain liquid over flood and cause dirty in when extruding.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
